Beyonce Knowles has already proved she is a woman who runs the world. So far this year, she has covered the January issue of GQ Magazine and performed at the presidential inauguration and the Super Bowl halftime show. She has a Vogue cover due in March, an upcoming tour and album, and she will headline the 2013 Essence Festival. But the most important thing on her mind is her 1-year-old daughter, Blue Ivy, whom she hopes one day will be inspired by her new documentary.

Knowles debuted her autobiographical film, Life Is But A Dream Tuesday night at Ziegfeld Theatre in New York City that takes a no-holds barred look at the various moments in the Countdown singer's life, detailing her miscarriage, rumors of her faking her pregnancy and firing her father as her manager. The film stems from Knowles' personal conversations she had using a video camera on her computer over the last couple of years.

"I hope that she will see all of the beautiful times (and) all the tough times that led up to her being here," the singer said told AP Tuesday night at the New York premiere of her upcoming HBO documentary.

"I'm hoping that ... it can comfort her and inspire her in her life when she needs it," she added.

Up until now, the 31-year-old singer had been private about her life in the past, but she felt that the time was right to share with people how she really felt. Knowles claimed the process of talking into a camera to communicate her thoughts out was her way to heal.

"I really grew so much," she said. "This movie has really been my therapy. I've healed from so many wounds and I've been able to understand why some of the things I've been through, why I went through, so feel really proud, and hopefully I can inspire other people."

In the March 2013 of Vogue, which features the superstar on the cover, the singer gushed on motherhood and how family changed her life.

"I feel like I have something that has grounded me so much more," she said. "Family has always been important. I've always had my mother and my father and my husband. But it's just... [she paused] Life is so much more than...it's not defined by any of this."

Despite her busy schedule, the Countdown singer said she always finds time for her little girl, calling the 1-year-old her "best friend."
